I think, you have little misconception regarding 100% deduction u/s. 80G and income tax payable.
Its not that by donating in amount u/s. 80G will reduce your total tax liability, but partially to the extent over the income to be deducted as donation.
For example :
your tax liability is 1 lakh and suppose you are under 30% slab. (simple example without cess etc.)
By donating 1 lakh under 80G(with 100% deduction organizations), your tax liability will reduced by 30000 and net tax payable will be 70K
